The invention discloses a remote control type line ON/OFF switch which comprises a support structure and an ON/OFF structure. The support structure comprises a base plate, two groups of switch springs, a guiding plate and a control system, the two groups of switching springs are arranged on the base plate, the guiding plate is arranged on the base plate vertically, and the control system is arranged on the support structure. When the switch is opened, a limiting pin of a limiting relay in the upper of a limiting plate shields a knife blade of the switch. If the switch needs to be closed, a remote controller communicates with a control unit to close the knife blade of the switch. A driving motor runs, a leading screw rotates to drive a driving nut to move downwardly, a spring is compressed,and when the spring is compressed to a limit position, the driving motor stops rotating, the control system controls motion of the limiting relay in the upper of the limiting plate, the limiting pinis pulled out of a limiting hole, the knife blade of the switch falls rapidly under effect of the spring, the two switch springs are connected, a limiting relay in the lower of the limiting plate moves, and the corresponding limiting pin is inserted into a limiting hole.
